Title: Electrostatic chuck attaching/detaching confirmation method
Inventor: NAKASUJI YUZURU
IPC: H02N13/00
Filed: 1997-12-03
Abstract: PROBLEM TO BE SOLVED: To enable confirmation of attaching/detaching in a short time by accurately discriminating attaching/detaching operation, independently of the state of the bonding surface of an Si wafer or the like, by making the amount of charge stored in the electrostatic chuck as a reference. SOLUTION: An electrostatic chuck 1 consists of a substrate 1c, an electrode 1b and an insulating layer 1a. The amount of charge stored between the electrode 1b and a wafer 2 is measured. The attaching operation is confirmed by detecting that the current value which initially increased when a voltage was applied to the electrode has practically returned to zero. The detaching operation is confirmed, when the applied voltage is decreased to lower than or equal to 1/10 the value at fixing.
